Asked whether Chelsea had enough quality at present to fight for the title, Sarri said: "No, not in this moment. We have to improve in the defensive phase, and I'm not talking about only the defenders.

"The defensive phase of all the team is all the players. And if we press very high, we are able to do well.

"But, at the other moments, when we are not able to press in the other half, we are in trouble.

"We did really very well in the first 25 minutes today. But we need to continue to press and press in the other half. Otherwise, for us, it may be a problem. We need to improve and I hope we will be able to play 90 minutes like the first 25 in a few months."
